2.3 Power Consumption
The M.2 drive receives DC power (+3.3V) through the standard M.2 interface.
NOTE Here is more information on Power:
NVMe Autonomous Power States are not supported.
Typical power measurements are based on an average of drives tested
under nominal conditions.
Maximum power is defined as RMS over 100ms.
2.4 Power Loss Data Protection
If power is interrupted, at any time while data is being programmed into the NAND, it is possible that data loss may
occur. This can cause drive errors to be reported to the host. To prevent these errors from occurring, XM1440
implements an energy storage solution called Power Loss Data Protection. This is a circuit that maintains power to the
NAND while it is being programmed, even if power to the system is interrupted. By supporting Power Loss Data
Protection, the drive assures data integrity in the drive is preserved, preventing the loss of data and the reporting of
drive errors to the host.
2.5 Out of Band Management (SMBus)
XM1440 provides out of band management by means of SMBUS interface.
2.6 Basic Management Command
SMBUS accesses an NVM Express Basic Management Command page as listed below through address 0x6A.

Description
0
00
Length of Status: Indicates number of additional bytes to read before encountering PEC. This value should always
be 6 (06h) in implementations of this version of the spec.
01
Status Flags (SFLGS): This field indicates the status of the NVM subsystem.
SMBus Arbitration – Bit 7 is set ‘1’ after a SMBus block read is completed all the way to the stop bit without bus
contention and cleared to ‘0’ if a SMBus Send Byte FFh is received on this SMBus slave address.
Drive Not Ready – Bit 6 is set to ‘1’ when the subsystem cannot process NVMe management commands, and the rest
of the transmission may be invalid. If cleared to ‘0’, then the NVM subsystem is fully powered and ready to respond to
management commands. This logic level intentionally identifies and prioritizes powered up and ready drives over
their powered off neighbors on the same SMBus segment.
Drive Functional – Bit 5 is set to ‘1’ to indicate an NVM subsystem is functional. If cleared to ‘0’, then there is an
unrecoverable failure in the NVM subsystem and the rest of the transmission may be invalid.
Reset Not Required - Bit 4 is set to ‘1’ to indicate the NVM subsystem does not need a reset to resume normal
operation. If cleared to ‘0’ then the NVM subsystem has experienced an error that prevents continued normal
operation. A controller reset is required to resume normal operation.
Port 0 PCIe Link Active - Bit 3 is set to ‘1’ to indicate the first port’s PCIe link is up (i.e., the Data Link Control and
Management State Machine is in the DL_Active state). If cleared to ‘0’, then the PCIe link is down.
Port 1 PCIe Link Active - Bit 2 is set to ‘1’ to indicate the second port’s PCIe link is up. If cleared to ‘0’, then the second
port’s PCIe link is down or not present.
Bits 1-0 shall be set to ‘1’.
02
SMART Warnings: This field shall contain the Critical Warning field (byte 0) of the NVMe SMART / Health Information
log. Each bit in this field shall be inverted from the NVMe definition (i.e., the management interface shall indicate a
‘0’ value while the corresponding bit is ‘1’ in the log page). See the NVMe specification for bit definitions.
If there are multiple controllers in the NVM subsystem, the management endpoint shall combine the Critical Warning
field from every controller such that a bit in this field is:
Cleared to ‘0’ if any controller in the subsystem indicates a critical warning for that corresponding bit.
Set to ‘1’ if all controllers in the NVM subsystem do not indicate a critical warning for the corresponding bit.
03
Composite Temperature (CTemp): This field indicates the current temperature in degrees Celsius. If a temperature
value is reported, it should be the same temperature as the Composite Temperature from the SMART log of hottest
controller in the NVM subsystem. The reported temperature range is vendor specific, and shall not exceed the
range -60 to +127°C. The 8 bit format of the data is shown below.
This field should not report a temperature when that is older than 5 seconds. If recent data is not available, the
NVMe management endpoint should indicate a value of 80h for this field.
Value Description
00h-7Eh Temperature is measured in degrees Celsius (0 to 126C)
7Fh 127C or higher
80h No temperature data or temperature data is more the 5 seconds old.
81h Temperature sensor failure
82h-C3h Reserved
C4 Temperature is -60C or lower
C5-FFh Temperature measured in degrees Celsius is represented in twos complement (-1 to -59C)
04
Percentage Drive Life Used (PDLU): Contains a vendor specific estimate of the percentage of NVM subsystem NVM
life used based on the actual usage and the manufacturer’s prediction of NVM life. If an NVM subsystem has multiple
controllers the highest value is returned. A value of 100 indicates that the estimated endurance of the NVM in the NVM
subsystem has been consumed, but may not indicate an NVM subsystem failure. The value is allowed to exceed 100.
Percentages greater than 254 shall be represented as 255. This value should be updated once per power-on hour and
equal the Percentage Used value in the NVMe SMART Health Log Page.
06 : 05 Reserved: Shall be set to 0000h.
07
PEC: An 8 bit CRC calculated over the slave address, command code, second slave address and returned data.
Algorithm is in SMBus Specifications.

NOTE Here is more information on Airflow:
Airflow approach is from thermal ground screw to M-key connector. No
heat sinks are used in this specification.
Thermal throttling is activated to protect critical components from
damage. The host observes a reduction in power and therefore
performance until PCB temperature lowers. When the PCB temperature
decreases to an acceptable temperature, thermal throttling deactivates,
and performance returns to normal.
2.8 Reliability
NOTE Here is more information on MTBF:
MTBF specification is based on these assumptions for Enterprise Storage
System environments: 8760 power on hours per year, 250 power on/off
cycles per year, and nominal voltages. The drive achieves specified MTBF
when operating in an environment that ensures the case temperatures do
not exceed the temperature specifications.
Data Retention is the time that NAND retains data at maximum rated
endurance
2.9 Endurance
NOTE Endurance rating is the expected amount of host data that can be written by
product when subjected to a specified workload at a specified operating and
storage temperature over the specified product life. For the specific workload to
achieve this level of endurance, please refer to JEDEC Specification JESD218.
Terabyte Writes is defined as 1x1012 Bytes.

5.0 Standards and Reference Documents
5.1 Standards
The Seagate® Nytro® XM1440 family complies with Seagate standards as noted in the appropriate sections of this
manual.
The drives are recognized in accordance with UL 60950-1 as tested by UL, CSA 60950-1 as tested by CSA, and EN60950-
1 as tested by TUV.
The security features of Self-Encrypting Drive models are based on the “TCG Storage Architecture Core Specification”
and the “Storage Work Group Storage Security Subsystem Class: Opal, Version 2.00”.
5.1.1 Electromagnetic compatibility
The drive, as delivered, is designed for system integration and installation into a suitable enclosure prior to use. The
drive is supplied as a subassembly and is not subject to Subpart B of Part 15 of the FCC Rules and Regulations nor the
Radio Interference Regulations of the Canadian Department of Communications.
The design characteristics of the drive serve to minimize radiation when installed in an enclosure that provides
reasonable shielding. The drive is capable of meeting the Class B limits of the FCC Rules and Regulations of the
Canadian Department of Communications when properly packaged; however, it is the user’s responsibility to assure
that the drive meets the appropriate EMI requirements in their system. Shielded I/O cables may be required if the
enclosure does not provide adequate shielding. If the I/O cables are external to the enclosure, shielded cables should be
used, with the shields grounded to the enclosure and to the host controller.
5.1.1.1 Electromagnetic susceptibility
As a component assembly, the drive is not required to meet any susceptibility performance requirements. It is the
responsibility of those integrating the drive within their systems to perform those tests required and design their
system to ensure that equipment operating in the same system as the drive or external to the system does not
adversely affect the performance of the drive.
5.1.2 Electromagnetic compliance
Seagate uses an independent laboratory to confirm compliance with the directives/standards for CE Marking and C-Tick
Marking. The drive was tested in a representative system for typical applications and comply with the Electromagnetic
Interference/Electromagnetic Susceptibility (EMI/EMS) for Class B products. The selected system represents the most
popular characteristics for test platforms. The system configurations include:
Typical current use microprocessor
Keyboard
Monitor/display
Printer
Mouse
Although the test system with this Seagate model complies with the directives/standards, we cannot guarantee that all
systems will comply. The computer manufacturer or system integrator shall confirm EMC compliance and provide the
appropriate marking for their product.

Marking, it complies with Chinese National Standard (CNS) 13438 and meets the Electromagnetic Compatibility (EMC)
Framework requirements of the Taiwanese Bureau of Standards, Metrology, and Inspection (BSMI).
5.1.8 European Union Restriction of Hazardous Substances (RoHS)
The European Union Restriction of Hazardous Substances (RoHS) Directive restricts the presence of chemical
substances, including Lead (Pb), in electronic products effective July 2006.
A number of parts and materials in Seagate products are procured from external suppliers. We rely on the
representations of our suppliers regarding the presence of RoHS substances in these parts and materials. Our supplier
contracts require compliance with our chemical substance restrictions, and our suppliers document their compliance
with our requirements by providing material content declarations for all parts and materials for the disk drives
documented in this publication. Current supplier declarations include disclosure of the inclusion of any RoHS-regulated
substance in such parts or materials.
Seagate also has internal systems in place to ensure ongoing compliance with the RoHS Directive and all laws and
regulations which restrict chemical content in electronic products. These systems include standard operating
procedures that ensure that restricted substances are not utilized in our manufacturing operations, laboratory
analytical validation testing, and an internal auditing process to ensure that all standard operating procedures are
complied with.
5.1.9 China Restriction of Hazardous Substances (RoHS) Directive
This product has an Environmental Protection Use Period (EPUP) of 20 years. The following table contains
information mandated by China's "Marking Requirements for Control of Pollution Caused by Electronic
Information Products" Standard.
"O" indicates the hazardous and toxic substance content of the part (at the homogeneous material level) is lower than
the threshold defined by the China RoHS MCV Standard.
"X" indicates the hazardous and toxic substance content of the part (at the homogeneous material level) is over the
threshold defined by the China RoHS MCV Standard.
